elements of the window casing for conducting the Referring to the annexed drawing d o e slidable shutter from the lowered to the lifted-particularly to Figures 1, 2 andwi, the window position and vice-versa so as to avoid any dif structure according to our invention comprises ficulty in its operation. an upper portion constituting the proper win-' dow 1 and a lower portion or parapet 2, both portions being connected to each other by a cross bar or sill-board 3, extending transversally between the side elements 4 of the window casing, which latter is completed by the upper cross bar 5. The side elements 4 are elongated downwardly beyond the sill-board 3 constituting an additional frame which is covered by panels 2 so as to form a hollow parapet serving to completely re-.

ceive and hide a slidable, flexible shutter 6 of any convenient form when the same is moved into its lowered position.

The shutter as shown in Figures 1 and 2 is of the class comprising a plurality of horizontal rods conveniently connected to each other and having longitudinal mortices 7 for ventilation purposes.

The slidable shutter 6 is disposed at-the outer face of the window, and when it is lowered, it remains completely hidden within the hollow parapet 2. In order tosecure an easy operation of the shutter and for the purpose of avoiding any difficulty in lifting and lowering the same, its side end portions extend into-the guide groves 8 provided on the inner surface of the side elements 4 at both sides of the window. The guide groves may be constituted either by special U- shaped metal bars 9 conveniently attached to the side elements 4 by means of screws 10 or like fastening means, or the same are out directly in the material of said side elements, as preferably donein the lower portion of the window structure. These guide groves 8 start immediately below the upper cross bar 5, go straight-down traversing the sill-board 3 into the parapet 2 and therein form a double loop as properly shown in Figure 2.

' It will be appreciated that the length of these guide groves 8 within the parapet 2 is identical to the distance of the upper cross bar 5 and the sill-board 3, so that the downward movement of the shutter 6 will be limited by the end point 11 of the guide groves 8 and that theshutter in its lowered position will remain hidden in the parapet.

Thesill-board 3 is also made partially hollow so as to provide the necessary space for hiding and fixing therein the shutter operating mechanism, composed of an angular gear 12 conveniently mounted in a bracket or like support 13 and transmitting the motion of a detachable handle (not shown) to the elongated shaft 14 supported by plates 15 fixed to the side elements 4 of the window casing. On said shaft 14, near the ends thereof, on each side of the structure there is provided a gear 17 operating an endless belt 18, one of the gear forming wheels being mounted on a supplementary'shaft l6. Said belt passes over a loose pulley 19 secured to the side ele.

ments l, by means of the shaft 20 and a supporting plate 21, immediately below the upper cross bar 5. This belt is connected to the upper shutter rod 22 in any suitable manner, preferably by means of a conveniently bent metal bar (not shown). Said pulley 19 determines the way of said endless belt 18 from the gear 17, Figure 3, to the head portion of the window structure, Figures 1 and 2. V

For the correct understanding of the arrange-, ment of the gear 17, belt 18, and loose pulley '19 with respect to the shutter 6, the side end portions of which extend into the guide grove 8 (Figure 2), it may bementioned that the latter in the upper portion of the structure comprises the U-shaped metal. bar 9, and beside this bar there is a second longitudinal grove 23, in which at the upper end thereof the support 21 is fixed and which provides the necessary passage. for the belt 18, this grove communicating with the cavity in the sill-board 3, in which the gear 17 and its bracket 15 are mounted.

The U-shaped grove member 9, at its lower end near the sill-board 3, is uncompleted in as 7 far as its outer wall is recut for a short distance and the grove thus is left open, so that at this point the shutter may bemoved outwardly, ii

the same is in its lifted position and the lower shutter rod 24 is found at the level of an angle iron 25 provided on the sill-board 3, as shown in Figure 5. The displacement of the lower shutter end or of the lower shutter rod 24 maybe effected by means of a' bolt or other push member 26 provided with a return spring 27- to such an ex-,

tent that the longitudinal grove 28 provided in the rod 24 may engage the angle iron 25, which thus retains the lower shutter rod or shutter end in an outwardly inclined position and prevents water or the like from-entering the lower portion of the window structure, if the shutter is'in lifted position. j v

Referring particularly to Figure 1, showing a cross section of the upper portion of thewindow structure and the proper window to be opened 7 around the hinge 2 9 and-to be firmly closed by means of the handle 30, it will be noted from this view that the additional grove 23 leaves a free space between the window and the guide mem bers' 8, said space being sufficient for inserting therein a removable frame comprising a metallic screen (not shown), which will be considered useful for preventing gnats and mosquitoesfrom entering the house whenthe window is open, the

shutter being either in lifted or lowered position.

It has to be understood that the present invention is by no means limited to'the specific embodiment as hereinbefore described and as shown on the accompanying drawings, but that modifi cations may be introduced as tothe arrangement and form of the different component parts. of the device and in other respects, without departing from the scope of the invention as set forth in the following claims.
